I could probably figure this out by myself... But I thought I would ask the experts just in case someone has experienced this problem before. 2002 Merc 350 Mag MPI horizon / Bravo 1 leg... Last night after a full day on the water the serpentine belt came off, After closer inspection I discovered that the pully on the water pump had moved forward pulling the belt out of alighnment with the rest of the pullys. I also noticed there was water leaking from the water pump. I was able to kick the pully back into alignment and re-install the belt (which was now very loose) I was able to limp 2 hours back to the dock stopping 3 times to re-install the belt and let the engine cool down due to over heating. It was dark when this all happend so I haven't had a chance to really look at everything (stuck in the office now) Does any one know why the water pump pully would move forward out of alignment with the rest? Also my Volts dropped while making my way back home so I assume the alternator was not charging the system up. I assume the water pump is also shot?
